Strong® Carbon Series X-Bracket Adapter for Articulating Mounts
We’ve made this X-Bracket adapter as versatile as possible to fit today’s unpredictable VESA patterns and TV connections. Compatible with Medium, Large, and XL Strong® Carbon Series Articulating Mounts. 
Carbon Series Compatibility
These 400 x 400 adapter plates are compatible with the Strong® Carbon Series Medium, Large, and XL Articulating Mounts.
VESA Pattern Versatility
We know that TV manufacturers are unpredictable with placement of VESA patterns and inputs/outputs on the back of the TV. These accessory brackets are helpful if the H-pattern on the Large or XL mounts are interfering with these important functions and the X-Pattern adapter helps in avoiding them.
